Specification of Letters Patent.

Patented Dec. 26, 19ML Application filed April 10, 1914. Serial No. 830,946.

To all whom t may concern:

Be it known that I, KATHERINE It. OKANE, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Diiplicating-lachines, whereof the following is a specification, reference being had to the accompanying drawings:

My improvement is particularly applicable to printing machines of the type known commercially. as the multigraph; comprising a rotary printing drum having a series of undercut channels in its curved surface extending parallel with its axis to receive complementary shaped flanged type which said drum presents in opposition to the other member of the printing couple. As ordinarily constructed, all of the letters, numerals, punctuation marks, etc., are printed from respectively separate individual type which must be set in said channels which extend parallel with the axis of the curved sui'- face in which said channels are formed. Consequently, in order to print tabular work, including vertical columns of figures, decimal points, ditto marks, etc., in which each character is presented by an individual type, it is necessary to set said type individually in successive channels extending parallel with the axis of the printing drum and to provide means for maintaining such separate type in a plane at right angles to said axis, for. unless said type are accurately set and provided with means to hold them in such alinement, they present an irregular appearance.

rTherefore, it is an object of my invention to provide such a machine with means to present a series of figures or other printing characters in lines at right angles to the linesl of words, and, as hereinafter described, such means include a bridge type curved to litI circumferentially upon said printing drum and preferably having means fitting in said undercut channels therein adapted to retain it in set position, said bridge type having a plurality of distinct printing faces respectively radially coincident with the channels aforesaid; so that the series of printing faces carried by said bridge type extending circumferentially with respect to said curved drum surface, which is formed to carry rows oftype parallel with its axis, shall be respectively presented in alinement with such rows. Letters Patent of the United States #1,085,627 were granted to me February 3, 1914 broadly claiming such bridge type.

The present invention relates to such type arranged to carry a plurality of distinct printing faces separably mounted therein so that they may be set in variable order on said bridge type. As hereinafter described, the printing faces arranged to be set in variable order on the bridge type may be in unitary relation with type bodies such as the ordinary type for the multigraph, each having flanges engaging an undercut channel in the drum, or said faces may be devoid of any means to directly. engage the drum, and only have means to engage the bridge type.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings; Figure I is a fragmentary plan view of a portion of a printing drum carrying ordinary individual character type, some set directly in the channels of said drum and some in one of my improved bridge tvpe which has projections engaging the channels in the drum, said bridge type being like said individual type in that it is not removable radially. Fig. II is an end view of the elements shown in Fig. I. Fig. III is an elevation of the bridge type body shown in Fig. I. Fig. IV is an elevation of the bridge type cover plate shown in Figs. I and II. Fig. V is an enlarged plan View of the left hand end of the bridge type body and cover plate shown in Figs. I and II. Fig. VI is an elevation of the bridge type body indicated in Fig. V, showing how a rib thereon is engaged with the groove of an ordinary multigraph type. Fig. VII is a transverse sectional view of the bridge type body and cover plate, taken on the line VII, VII in Fig. V, showing said multigraph type fitted therein. Fig. VIII is an elevation of a bridge type body, similar to Fig. III but having projections to engage the drum so shaped that it may be set in or removed from the drum channels radially. Fig. IX is an elevation of a cover plate for the bridge type shown in Fig. VIII. Fig. X is a fragmentary elevation of a stamped form of bridge type body, having stamped ribs adapted to lit the type groove. Fig. XI is an elevation of a bridge type body having projections to engage the channels of the drum, differing from those shown in Figs. III and VIII. Fig. XII is an elevation of a cover platel for' the bridge Vtype shown inv shown in Figs. I toV VII;

shown in Fig. III, said Fig. XI. Fig. XIII is a fragmentary plan view of a bridge type body having a cover plate with a resilient member detachably connecting it therewith. Fig. XIV is a fragmentary plan view of a stamped sheet metal bridge type and cover plate having resilient interengaging means. Fig. XV is a fragmentary plan view of a portion of a printing drum with ordinary individual character type set directly therein and a modified form of my improved bridge type set therein; said bridge type having separable faces devoid of means directly engaging said drum. Fig. XVI is an end view of the elements shown in Fig. XV. Fig. XVII is a fragmentary enlarged plan view of the bridge type shown in Fig. XV, showing resilient means for holding a lprinting face therein. Fig. XVIII is an elevation of the bridge type shown in Fig. XVII. Fig. XIX is a transverse sectional view of the bridge type, taken on theline XIX in Fig. XVII.

Referring to the form of my invention the rotary printing drum 1 has the undercut channels 2 extending in its perimetal curved surface parallel with itsA axis. The ordinary letter type 3 and numeral type 4 have flanges 5 complementary to and adapted to fit in any one of said channels; said type having means to engage but one of said `channels at a time and having a printing face presenting but a single character. Said ordinary type?) and 4 each have a groove 6 extending parallel with said channels, exterior thereto, and, as shown in Figs. I and II, a series of said type 4 are held in a vertical column, extending circumferentially on said drum 1, by engagement in the bridge type-8 which has a seriesV of peripheral recesses 9 in which said type 4 are respectively fitted, with their grooves 6 engaged with the ribs 10 of said type body. Said type 4 are retained in said type body 8 by the cover plate 11. As best bridge type body 8 has flanges 12 projecting radially therefrom complementary to and adapted to fit in any one of said channels 2, and, as best shown in Fig IV, said cover plate 11 has similar projecting flanges 13. Said projections l2 and 13, respectively on said bridge type body 8 and its cover plate 11, are of such configuration that such a bridge type cannot be radially insertedor removed with respect to the drum but must be set and removed therefrom by sliding it in the channels 2 from the end of the drum, like the ordinary type 3 and 4. Therefore, I find it convenient to provide a bridge type 15 and cover plate 16 with respective projections 17 and 18 so constructed and arranged that although they are adapted to fit in said channels 2 and engage the undercut ledges of the drum therein, they may be radially inserted and removed. as the greatest width of the hooked ends of said projections 17 and 18 are less than the least width of said channels 2. Y

Bridge typesuch as shown in Figs. III and VIII may be conveniently made of die cast'metal, the cover plates fo-r the same being conveniently formed of sheet metal stampings. However, bridge type bodies may be made of sheet metal stampings in lieu of castings, for instance, as shown in Fig. X the bridge type body 20 may be stamped from primarily plane sheet metal; the ribs 21 being stamped from the openings 22. The bridge type 15 and 20 shown in Figs. VIII and X, being provided with projections 17 and 23 which are flanged in but one direction, to engage the undercut channels in the drum 1, are intended to be set in said drum so that friction of the opposed member of the printing couple tends to displace said rules circumferentially in the direction in which the hooked ends of said projections extend; so that such friction tends to retain them in engagement with the drum, for if they are placed in the drum with the hooks extending in the opposite direction circumferentially, they may be displaced circumferentially by the stresses to which they are subjected during thel printing operation; such displacement being to thek extent that said projections 17 and 18 are narrower than the narrowest portions of said channels 2. However, it is unnecessary to provide the bridge type of my invention with any hooked flanges to engage the drum, as radial displacement thereof is prevented by the frictional engagement of the contiguous type or stops 24. Therefore, I find it convenient to provide bridge type 25, as shown in Fig. XI, with projectionsV 26 precisely fitted to the narrowest portions of the drum channels 2 so as to prevent circumferential displacement of such bridge type, regardless of the position in which they are placed in the drum. The cover plate 28, for said bridge type 25, has similar projections 29 as shown in Fig. XII.

In each of the forms of my invention above described, the cover plates 11, 16 and 28 are disconnected fromV their respective bridge type 8, 15 and 25, being merely held in cooperative relation therewith by the contiguous type or line stops. However, as shown in Fig. XIII, such cover plates may have means detachably connecting them with their respective bridge type bodies, including resilient members 32 at respectively opposite ends thereof. Such bridge type bodies and cover plates may be connected and disconnected by relative radial movement with respect to the drum, without flexing said members 32, or may be connected or disconnected by relative axial movement such as to flex said members 82. Such construction and arrangement maybe conveniently employed where the body of interengaging moese-4 sg the bridge type is formed of inflexible cast metal. However, when both the bridge type bodyvand cover plate are formed of sheet metal stampings, I prefer to provide them with resilient interengaging means such as shown in Fig. XIV, wherein the bridge type body 34 has a pair of oppositely counterpart fingers 35 resiliently engaging the oppositely counterpart fingers 36 on the cover plate 87.

Referring to the form of my invention shown in Figs. XV to XIX inclusive; the bridge type 40 has the undercut peripheral recess 4l arranged to hold in printing position the separable printing faces 42. Said type 40 has radial projections 43 which engage vthe undercut ledges in the channels 2 of the drum 1 as above described with reference to thev forms of my invention shown in Figs. VIII and X. Said drum being rotated in the direction of the arrow shown in Fig. XVI, during the printing operation, there is no tendency to circumferentially displace either said bridge type 40 or the separable printing faces 42 carried thereby; on the contrary, the frictional engagement of the other member of the printing couple tends to maintain said type and faces in proper position. However, in order to insure that said type will not be displaced in the opposite direction, I insert the resilient plug or linestop 24 at the open end of said bridge type 40 as shown in Figs. XV and XVI. It may be observed that said plug 24, which is conveniently formed of rubber, holds both said type 40 and the printing faces 42 thereon against circumferential displacement. However, when it is desired to employ in a type 40 a less number of printing faces than would fill the same, I find it convenient to employ the resilient line stop 45 shown in Figs. XVII, XVIII and XIX; said stop 45 is conveniently formed of resilient wire which frictionally engages the undercut recess 41 and constitutes a movable abutment for the end of the type face or faces 42 set in said bridge type 40.

Although the bridge types above described may be formed without any printing faces except those which are separably set therein,

I find it convenient, in some instances, to'

also provide them with printing faces immovable thereon; for instance, as shown in Figs. I, III, V and VII, the bridge type body 8 has the printing face 47 immovable thereon, said face being adapted to print a period or decimal point adjacent the separable type face. It is to be understood that .uch immovable printing faces on the bridge type may be of any desired configuration; for instance, as shown in Figs. XV to XIX inclusive, the bridge type may have a printing face 48 adapted to print a vertical column line.

I do not desire to limit myself to the precise details of construction and arrangement above described, as it is obvious that various modifications may be made therein without departing from the essential' features of my invention, as defined in the appended claims.
